Super hard Classes Question Example

=======================
==  EXAMPLE 1
===================

Make a Student and Staff

Make a common class: Human

class Human {
  //Common things for both Staff & Students go here
  int age, x, y;
  String fName, lName;
  int vacation;

  Human (String f, String l, int a){
     this.age = a;
     this.fName = f;
     this.lName = l;
     this.x = 0;
     this.y = 0;

     this.vacation = 0; //Suspension system
  }

  void walk (int a, int b){
     this.x = a;
     this.y = b;
  }
}

class Staff extends Human{
  float salary;
  int forksStolen;

  Staff (int age, String first, String last, float sal){
      super(first, last, age);
      this.salary = sal;
      this.forksStolen = 0;
  }

  boolean cP(String fN, String lN){
      //suspend student fName, lName

     for(int i=0; i < population; i ++){
         if(population[i].fName == fN && population[i].lName == lN){
             population [i].vacation = 5 + rand(5);
              break;
         }
     }

     boolean result = true;
     if(random(100) > 60) result = false;

     return result;
  }

}


class Student extends Human{
   float average;
   int[] marks;

   Student (String first, String last, int age){
        super(first, last, age);
        this.marks = new int[8];
        this.average = -1;
   }

   boolean HasFuture(){
        boolean res = false;
        if(random(100) > 50) res = true;
        return res;
   }

   void crashCar(){
        Guzy.vacation += 10 + rand(15);
        this.vacation += 30;
   }
}

Staff Guzy = new Staff("Mr", "GGGGG", 36);

Guzy.cP("Steve", "jobs");

Student[] population = new Student[2100];
population[0] = new Student("Steve", "jobs", "900");
population[1] = new Student("Steve", "JobS", "901");
population[2] = new Student("Steve", "joBs", "902");

Syed = new Student("Syed", "???", -1);
Syed.crashCar();

Syed.crashCar()
population[1].crashCar();

==  EXAMPLE 2
===================

Good cop vs Bad cop



class Cop {
  float salary;
  boolean hasGun;
  Hat myHat; //Assuming we had a Hat class
  String name;
  int dayToRetirement;

  Cop (String n, float sal){
       this.name = n;
       this.salary = sal;
       this.hasGun = true;
       this.myHat = new Hat();
       this.daysToRetirement = 5;
   }

   boolean eatDonuts(){

       return true;
   }

   void tempFate(){
       print("I've only got " + this.daysToRetirement + " to retirement");
       print("Can't wait to go home to my wife and kids");
   }
}


class GoodCop extends Cop {
   boolean smile;
   
   GoodCop (String nm, float dollars){
      super(nm, dollars);
       this.smile = true;
   }

   void showMercy(){
       print("have some water?");

   }

}



class BadCop extends Cop {
   int attitude;
   boolean looseCannon;

   GoodCop partner;

   BadCop (String name, float sal, int att){
        super(name, sal);
        this.attitude = att;
        thsi.looseCannon = true;

       // this.partner = new GoodCop("Alex Murphy", 0);
       this.partner = dept[floor(random(dept.length))];
   }


   void talkSense(){
      if(random(100) > 80) this.looseCannon = false;

   }
}




BadCop riggs = new BadCop("Riggs", 20000);

riggs.talkSense();

riggs.partner.showMercy();
riggs.tempFate();



GoodCops [] dept = new GoodCop [20];





Thinkie Task  (Monday)
- 3 quick thinkie style questions, but not so thinkie as Algorithms (sorting)
- I will take best mark and ignore the other.



Things I include in the midterm mark
-> test + thinkie task
-> Review, Ball bouce, PEW PEW, anything other show me
